Bacteriological Profile of Acute Respiratory Infections in Children: About a Prospective Study at the Albert Royer Hospital in Dakar

摘要

Introduction: Acute Respiratory Infections (ARI) is a global public health priority. It is the leading cause of childhood morbidity and mortality, especially in developing countries. The main objective of this work was to look mainly at the bacteriological aspects of ARI in children in Senegalese hospitals. Methodology: We have been conducted a prospective descriptive mono-centric study over a period of one year (from July 1, 2017 to June 30, 2018) at the Albert Royer National child hospital in Dakar. A multiplex PCR (protein chain reaction) has been performed on nasopharyngeal swabs taken from all patients. This technique (viral RNA transcribed into DNA, then the DNA of the different pathogens is simultaneously amplified in the same tube by PCR Fast-tract ~(&reg) , multiplex). Results: During the study period, 109 patients were included. The hospital prevalence of acute respiratory infections was 3.7%. The mean age was 23.7 months with extremes between 1 month and 144 months. Peaks of consultations were found in the months of August, March and April with 22%, 15.6% and 12.8% respectively. Fever, respiratory distress and pulmonary condensation syndrome were the main signs found in our patients. Bacteriology was positive in 82.6% of samples and the most frequently found bacteria were Streptococcus pneumoniae in 38.5%, Haemophilus influenza b in 32.1% and Moraxella catarrhalis in 25.7%. Pneumonia was the main diagnosis, found in 61 cases, a prevalence of 59.9%. The average length of hospitalization was 10 days. Lethality was 1.8% or 2 cases. Conclusion: Acute Respiratory Infections in children still remains a public health problem in developing countries; children under 5 years of age are the most affected hence the need to strengthen ARI control programs. The identification of germs is indispensable in treatment and epidemiological surveillance in our regions.
